ELECTRICAL ANNOUNCING ATTACHMENT ron-oasn-nnorsrnns.

To all whom it may] concern:

Beit known that I, THOMAS J. SULLIVAN, citizenof the United States, and residing at New- York, in the county of New York and State of New York, have invented certain new and useful Improvements in Fl lectrical Announcing Attachments for Cash- Registers, of which the following is a specification, such as'will enable those skilled in the art to which it appertains tomake and use the same.-

. The object of this invention is to provide an electrically operated attachment for cash registers which will audibly announce by means of bells or similar devices the amount represented by a depressed key, or the amount shown on the face of the cash register at each operation thereof, and with these and other objects in ,view the invention consists in a device of the class specified conas hereinafter described and claimed.

'The invention is fully disclosed. in the following specification of which the accent-- panying drawings form a part, in which the separate parts of my attachment. are designated by suitable reterence characters in each of the views, and in which Figural is a front view of a box or case containing part of the operative mechanism of my improved attachment for cash register machines, part of the construction being shown in section, and said view showing I also diagrammatically a part. of the circuits employed and two of the keys of a cash regfl ister machine.

to one bank of the keys of a cash register machine, and Fig. 7 a VIEW similar to 'Fig. 6 but showing a modification.

Various forms of indicating devices liave'60' been employed in cash registers, but: the yalue of the usual visual indication is limited masmuch as it is viewable only from certain directions. Constructional limitations c'learly prevent the employment of indicators of tc very large size, and with the small indicators practicable to use, they are not readable fr m a very great distance.

This invention aims to utilize the sense of hearing as well asthe sense of sight by the '70 provision of bells or other sounding devices designed audibly to announce amounts or' other characteristics of transactions registered, eachsounding device ha'ving assigned' to it a single permanent value. With a de- 7 vice'of this type the sound or announcement of the sounding device may be heard at a considerable distance and the cnstomer'or other person may, therefore, determine the amount which has been registered, though far away from the machine. Int-his construction only a few sounding devices are employed, andto enable so few devices to dlgfimtely any one of a number ofells are arranged to ring in sucindicate amounts, cessionundercertain conditions and to ring a plurality of times. The control ofthe bells is furnished by the machine keys of V the cash register or like machine, and in the present embodiment, a motor driven-mechanism. serves to finally close contacts which control the bells. The motor circuit is closed by an initial key, though the five cent key'is In the drawing forming part specification I have shown in Fig.2 ,one bank of the keys of a cash register machine, this bank of keys beginning at ithe bottom" with an initial key A, above which are' placed, .in the orderna1ned, k eysrepresent ing five cents, ten cents, fifteen cents, twenty cents, twenty-five cents, fit'tycents, and one dollar, and for the purpose of this descrip' tion the initial key A and the dollar key are designated by the reference characters a and (1?, and these two keys are also shown in Fig. 1, whiletl'le entire bank of keys indicated diagrammatically in Fig. 6 and also in Fig. 7, and each of these keys is'provided with a. shank a having a laterally di- 1 rected' contact pin a.

Mostcash register machines as1now conprovided with screw holes 6 structed are provided with separate banks of keys provided with shanks which pass thrcugh the front wall of the casing of the machine 'and are operated by a push thereon, and the keys shown in'the accompanying drawing are similarly constructed and similarly operated, but only one bank of keys is shown.

In connection with each bank of keys I employ a metal strip 1), which is secured- 1 within the front wall of the casing of the machine adjacent to the shanks a of the keys, and these metal strips 1) are preferably by which they may be secured to the frontwall of the machine. The strips 2') are provided .at inter vals which correspond with the position of the keys with spring metal contact pieces 6 which range transversely of said metal strips, and which are insulated therefrom as shown at b, and the free ends of which are in the direction of the shanks of the keys the contact pins a, on the shanks of the keys are adapted to engage with these contact pieces I1 I also provide, as shown in Fig. 1, a casing c, in which the operative parts of my attachment are placed, and this casing may connection-with, above, or at either side of the cash register machine. In the bottom of the casing cin the form of construction shown are placed a plurality of battery cells 0 c and 0 two of said cells 0 and a being reserve cells, as shown in the accompanying drawing. The battery cells 0 c and c are placed in separate compartments beneath a horizontal false bottom or partition plate- 0 in thecasin'g c, and above said false bottom or partition, and in one end of the casing 0' is placed an electric motor cl, having a shaft (P. In line with the shaft 15 of the motor is placed a supplemental driving shaft (Z between which andthe motor is a suitable support (1 in which is mounted a coupling shaft d connected wit-h the supplemental shaft d by any suitable slip or friction coupling-cl, the coupling shaft d? is geared to the motor shaft 03 by any suitable reduction gear (Z placed ina suitable housing (i secured to the support (i and the supplemental shaft-d is supported at the end opposite the motor by a frame piece (Z secured to the casing c in any, desired manner.

Mountedon the supplemental or driving shaft (Z and secured thereto are a plurality of contact, or circuit making and breaking disks e, which equal in number the-cash keys of .the cash register machine, and in pracvt-ice, a series of these contact disks 1s employed in connection with each bank of keys. In the accompanying drawing there are seven cash keys in the bank of keys shown n Fig. 2, and, there are therefore shown seven of the contact disks on the shaftdt. These disks, for the purpose of be supported adjacent'to, or in electro-magnet 9' right by thereference characters c, 6 0", c,

or, c and 15 The contact disk 0 is shown separately in Fig. i, and is Pl'OVldt-{Clwlill the face thereof with a contact knob or pin Mounted adjacent to each of the contact disks 6 and in the same vertical plane therewith is an electro-magnet f provided with an arm f to which is pivoted an armature arm f weighted at one end as shown at f, and provided at its opposite end with an upwardly directed extension f adapted to make connection with the contact pin or All the contact disks 0 areshown diagrammatically in Fig. 3. The disk 6 is provided with two of the knobs or pins f, the disk c with one, the disk 0* with four, the disk (1 with three, the disk 0 with two, and the disk 6 with one, all of said contact pins'or knobs and the said pinsor knobs on the disks 6 forming contact points in connection with which the parts f of the corresponding arms f operate. The contact disk 6 operates in connection with the one dollar key a the contact disk 0 with the fifty cent key, the contact disk 6 with the twentyfive cent key, the contact disk c with the twenty cent key, the contact disk 6 with the fifteen cent key, the contact disk 0 with the ten cent key, and the contact disk 6 with the five cent key. It will be seen that the contact pins orkno-bs f on the separate disks are arranged at different radialpoints, this being necessary in the operation of the machine to prevent interference as hereinafter described, and in practice each of the disks 0 is preferably locked to the supplemental shaft 0Z by'a' set screw e The driving shaft 65 is provided, at the end opposite'the motor with a locking disk g, (Figsl and -5) having in its face a notch or recess 9 Pivoted to the casing c is an to enter said notch or recess, and supported over the end of the armature arm 9 is an,

Mounted on and connected with the casing c are a plurality of bells g, g and 9 provided within said casing with boxes 9 in which the vibratory mechanism is placed}. The bell is a twenty-five cent bell, the bell g a dollar bell and the bell '9 a five cent bell.

Referring to Fig. 6, it will be seen that connected to the positive pole .of the battery a is a lead wire it which is also connected to the supporting plate (Z of the driving shaft 61 Said support is connected with the release magnet g by a wire h 'and the magnet-g is connected with the positive brush of the motor by a wire k The contact making magnets f are connected in series by a wire h, which is connected. to the lead wire h, and each of said magnets is also connected to its corresponding contact piece 6 by a wire 7L In the construction'showlna the fivecent key isl'provided I with a dd-able Contact, one part of which is placed beldw the'contact piece bias shown at it. The contact h is connected with the negative brush of the motor, and the contact piece 6' of the initial key A is also con nectedwith the negative brush of the motor by a wire it; The contact part f. of each nets" f strip or plate I; is represented inFig. 6gby that part of the return wire it with wh ch the diske.

the contact parts Z) are con'nected and con-- stitutesa common return for all the keys. The magnets f are proyided with vertically extending stops m and the arms f of said magnets are provided .with stops n and these stops limit the movement of the armature arms f injboth directions. The stops t hold the armaturearnis'in proper position while the stops mprevent t'he extensions f 1 of the arms from coining in contact with The operation "of the apparatus, as shown in Figs. 1 to 6 inclusive, will be readily understoodfrom the foregoing description when taken in connection with the accompanying drawing and the'following statement thereof: Stippose' that it is desired to register one,

dollar." The dollar; key a? shown in Fig. l is depressed; this throws the contact pin a of said key into' engagement with the strip 7; and the latter is therefore depressed into contact with the strip or plate b. A circuit is .thus closed (Fig. 6) iirom the battery through the wireh, the .wire h, the dollar magnet j, the corresponding wire 7L5, thev corresponding contact piece 6 contact piece or strip 3) and return wlre h back to the battery. This operation energizes the dollar. magnet f and the" corresponding armature arm f is throwninto' the position shown in dotted lines in Fig. fl. The initial kevA is then forced in and a circuit is commotor d, and the magnet g5;

pleted through "the wire it, the wire h", the magnet 9 the wire 7d, the motor (Z and i the wire it back to thereturn wire it, or

in other words to the strip or plate 19.. The closing-of this latter circuit energizes the Said release magnet raises the armature arm g thereby he bells g", g and 9? are connected to a common return wire h? which leads to the negative pole of the;bat-' tery, and .it will .be understood, that the.

releasing the locking disk 9 aiid the niotor starts. The contact or circuit 'makin jan'd'l breaking disks e turn with the-shafttt and as 'said shaft turns, the dollar diske, in the above described-operation, makes con tact with the corresponding armature arm "f ,'and a: circuit is closed from the battery through the wire h, .suppprt 0Z shattvd contact-disk e, the' saitl -armature arm f wire it", the dollar bell g and. through, said bell to the return wire it and thus back to one contact pin f on the dollar disk 6. -'AS 'a'further illustration of the operatioxnsuppose it be desired to re 'ster t-hirt cents; In this case the twentyve cent key is depressed and the circuit is closed through the 'wire h, the Wire [23, the magnet f which corresponds with the twenty-five cent disk 6 the wire 72. of said magnet, the contact through the strip Z2 and return wire 72) 'to the battery. When the twenty-five cent key is depressed in this manner-it stays down and the five cent key is then depressed thus closing a circuit from the battery through the the battery.' This insures the ringing of said dollar bell .once because there is only piece. of the'twenty-five cent key and'back wire h, the wire 72, the fit'e cent. magnet f the corresponding wirefi the corresponding contact piece b ,,-the strip or plate I) to return wire, it and thus backto the battery; The five cent key is 'then further depressed and a circuit is closed from the battery through the wire' la, the wire 71?, the magnet. 9 the wire 71,, the motor? d and wire it, the contact piece hf, strip Z) and return wire It to the battery; The twentyfite cent key and the five cent key, in the first contact made by the five cent ke as above described actuate the corresponding magnets f thus throwing theparts f". of the .corresponding armature arms f into position to be engaged by. the contact pins or knobs f on the twenty-five andfive cent disks 6 and 67. The extreme-depression of the five cent key previously nention'ed energizes the release magnet g and releases the locking disk 9 and starts the motor. As the shaft (i rotates, the pin or knob f-on the twenty-five cent disk strikes the part f of the corresponding armature arm 7 and a circuit is closed through the wire 71, support (lithe shaft-(Z the twenty-five cent disk, the corresponding armature f, the wire it 'to the twenty-five cent bell g", which 'is rung once and thecircuit is also completed through the wire-71 back to the, battery. The five cent ,bell is operated exactly in the same manner by the five cent diskeflbut the arrangement of the contact pins or knobs on said disks, as shown in Fig. 3,is such, that the twenty-five cent bell is operated first. In the construction showh there are only three bells-employed, a dollar bell, a

twenty-five cent, and .a' five cent bell; and

for high pitch, and in practice, the deeper dollar key which controls the ringing of the .bell 9 it being -paratus, in which the keys are connected key is depressed, and this followed by the T when fifty cents or twenty cents is the keys themselves this arrangement of bells makes necessary the arrangement of contact pins or knobs f on the contact or circuit making and breaking disks 6 as herein shown and described, the fifty cent disk being provided with two, the twenty cent disk with four, the fifteen cent disk with three and the ten cent disk with two of said pins or knobs. Thereis no fifty cent bell, and when-it is desired to register and announce fifty cents, the fifty cent key is depressed and the initial key A; in this operation the fifty cent disk 0 is turned and the twenty-five cent bell is sounded twice. There is also no twenty cent bell and when it is desired to register and announce twenty cents, the twenty cent depression of the initial key A and the twenty cent disk is turned'and .the-fivecent bell circuit is broken and made four times by the four pins or knobs f on the twenty cent disk 0. There is also no ten cent hell, but the operation of registering and announcing .thisamount will be the same as registered and announced. lYhen there is an odd amount to be registered the initial key A is not used, but the five cent key wired as shown in Fig. 6, takes the place of it. In practice the dollar bell is given a deep pitch, the twenty-five cent bell a medium pitch, while the five cent bell is given a sharp pitched bell. employed is always rung first. All this enables any one within hearing quickly to calculate amounts indicated by said bells.

From the foregoing description itwill be seen that the amount keys are arranged in groups. and each group controls the opera tion of an announcing device such as a bell corresponding thereto. The first group consists of the keys from five to twenty inclusive and controls the hell 9, the said group comprises the twenty five and fifty cent keys and controls the bell g, while the third group as'shown consists of only the one understood that other keys may be employed to enlarge the capacity if desired. It will be understood, that any one will quickly become accustomed to the sound produced by these bells, and will recognize in an instant the character or amount represented by eachparticular 'bel-l. In F 1g. 7 of the drawing I have shown a modified form of wiring my improved ap-- in series by a wire 2', and said keys in them-' selves constitute a part of the return circuit and inthis form of construction the metal strip or plato b is not used, the wire 2' and taking the place of said 1 strip or plate; In this construction or form of wiring I have shown a combinat on key initial key or the five cent 71:, that is a key operating two of the magnets f at one depression. I have shown for illustration a thirty cent key. To announcethis amount I must sound the twenty-five cent bell and then the five cent bell. hen the key 73 is depressed it first contacts with the strip 7: this closes a. circuit from the battery through the wire it, -wire 71, magnet of the twenty-five cent disk, wire h, wire 7;", key 7c and return wire 5; a further depression of the key 7c closes a circuit through the wire 72., wire h magnet f of the five cent disk, wire it, wire Zr, contact strip-7.1 key 73 and return wire 2". The initial key is now depressed which closes acircuit through the magnet and motor (J, as previously explained. The remainder of the wiring in this form is the same as shown in Fig. 6.

Although I have described the parts f on the contact or circuit breaking and makingdisks 6 as knobs or projections it will be understood that any suitable contact making devices connected with the said disks 0.

and armature arms f that would operate in the same manner might be substituted therefor.

In the accompanying drawing I have shown in the casing c the circuit making and breaking wheels 0, the magnets f and their connected parts which ope ate in connection with only one bank of keys of the cash register machine, but it will be understood that in practice, these parts are duplicated for each bank of keys.

From the' foregoing description it will be seen that my improvement constitutes an attachment for cash' register machines by means of which amounts registered may be audibly announced or signaled in such manner as 'to be understood by anyone in the vicinity of the machine, or within the sound of the bells g, and g and it will also be apparent that my improvement is not limited to the exact. arrangement of bells shown and described, nor to the 'exactdetails of any features ot'the construtcion as shown and described, and various changes therein, and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

It will be understoodthat the shaft (5 moves through one revolution only each timethat the magnet and motor dare energized, and this occurs each time'thatv the key is operated, or a complete operation as herein described performed, it that the motor shaft (Z on which'a balance wheel 1) is placed may continue-to turn under its-.own 1nomentum,-after the supple.- Iuentalshaftd is locked by the nose 9* of the armature g engaging the notch or recess 9 in the disk 9; this operation being renwill also be understood dered possibleby means ofthe slip coupling (Z As long as the initial key is depressed, the motor circuit remains complete and the-motor therefore continues to turn. However, when the initial key is released, the motor Circuit is then broken-and the magnet g will then allow its armature to drop, whereby the nose 9* will drop into the notch when the latter reaches the positionof the nose. -The nose will meanwhile ride'on the wheel:g.-

i-klthough I have described thecash register keys as being of the form-provided with shanks movable through" the front wall of thecash register casing, it will be under stood that other styles of keys may be em ployed, and in such cases the details of the apparatus herein described which operate in connection with the keys will be correspond in'gly changed. It-will also be apparentthat thcughl have described an electro-motorfor operating the. shaft (P, a spring or other m o-- tor may be employed, in which event certaln details of the apparatus will be changed in orderto comply with the changes in the style of the motor employed.
